For yacht owners who want to summon a crew member but do not want to be bothered with dialing a phone or navigating a touch panel, there is the Ming wireless steward call system (www.mingsystem.com). The Ming, a portable 2-inch-tall cylindrical device that operates on its own or syncs with a yacht’s existing communication network, enables passengers to alert the crew just by pressing its one button. The Ming can be customized to match the yacht’s decor or made with any of a variety of precious metals and exotic hides. The starting price for a single Ming, excluding setup costs, is about $2,300.
